The influences of variable thickness, material property, length-to-thickness ratio, boundary condition on bending and free vibration responses are investigated and discussed in detail through several numerical examples.
The influences of the volume fraction index, the different estimation method of the material properties, length scale parameter, the aspect ratio and the Poisson effect on the static bending behavior are examined.
Influences of gradient indices, boundary conditions, temperature distributions, material properties, length-to-thickness ratios on the behavior of FGM plate are discussed in details.
In more detail, similar to the design strategy we have suggested as being followed under constant amplitude (CA) loading, the VA linear-elastic formalisation of the TCD proposed here takes as a starting point the assumption that the critical distance value is a material property whose length decreases with increasing of the number of cycles to failure.
According to the philosophy on which the linear-elastic TCD is based, the adopted critical distance is treated as a material property whose length increases as the number of cycles to failure decreases.
The dependence of Mode I and II stress intensity factors of single and multiple interface cracks on fiber and matrix material properties, crack length and distance between cracks are investigated.
The effects of the material properties and length of the plate on the flow-induced deformation are briefly discussed.

Secondly, a parametric study is performed to demonstrate the influences of the values of dimensionless length scale parameter, material property gradient index and length to thickness aspect ratio on the linear and nonlinear natural frequencies of FGM microbeams.
